Poly bushing comparison
I've decided to rebuild my suspension with polyurethane bushings.
(I know there is always a debate between rubber and poly and some people will disagree with my choice, but that's not the point of this thread.)
My question is: Is there a particular manufacturer who is considered to be better than others when it comes to poly bushings? How do I avoid the junk out there?

We have handled Energy Suspension and Prothane, both quality brands. We currently stock Prothane and our customers have been very satisfied with it.

Go with Energy Suspension. I know from personal experience that they do actually tune the durometer (hardness) rating of their bushings to the specific application. Their T-arm bushings for example are noticeable softer than their A-arm bushings.
It's the guys that go with the mystery off-brands that always tell you that polys are all hard as rocks and crack apart etc. etc. etc.

I have I have run Del-A-Lum bushings on more cars then I can count; both on clients cars and my own; not once have I been unhappy with the ride.
Energy suspension runs 70 or 88 durometer urethane for the majority of their bushings. They don't do custom tuning per se.

I am working on my 89 installing new fuel lines. While having it all torn apart, I decided to replace all the bushing and went with superpro. They all installed easily except for the batwing bushings which were a little more work, but I did not remove it completely from the car. It would probably be much easier if removed and done with a shop press. I do not have mine back on the road yet, so I cannot comment on handling
I bought mine from https://www.corvettepartscenter.com/. They are the individuals who worked with superpro to get the bushings designed and made for the C4. There is a You Tube video from these guys. Just search superpro and you should find it.
